Sr. Software Developer - Core Platform
About The Position
TripArc's ADX platform is building the next generation of its core booking infrastructure — and getting it right, every time, at scale, is not optional. This Senior Backend Developer role sits at the heart of that build, on a core platform pod responsible for delivering the commercial and transactional capabilities that power the advisor experience and the business behind it. The roadmap is concrete, with a well-defined sequence of initiatives, each with delivery windows. You'll own meaningful slices of that build, working directly with Product and UX to design, implement, and ship backend services that are reliable, accurate, and built to last. This is a backend-focused role. You'll work primarily in .NET Core microservices and SQL Server, with Angular touchpoints where needed. Experience in complex transactional or commercial domains is expected — you understand how to build systems where correctness and reliability are non-negotiable.
Requirements
- 5+ years with C# / .NET Core — you've built production microservices and know how to make them operationally sound
- Experience in transactional or commercial domain work — you've built systems where accuracy, state management, and edge case handling are critical, and you understand what that demands architecturally
- SQL Server fluency — complex schemas, stored procedures, query optimization, and the discipline to get financial data right
- RESTful API design and third-party service integration experience
- Event-driven architecture experience — Azure Service Bus, NServiceBus, or equivalent messaging patterns
- Strong understanding of data correctness requirements — audit trails, state consistency, and the discipline to build systems where precision is non-negotiable
- Comfort working in a mature, high-volume platform where correctness is non-negotiable
- You use AI development tools — Claude, Copilot, etc. — as standard workflow, not novelty
Nice To Haves
- Angular experience — enough to contribute to advisor-facing payment UI components
- MongoDB, Docker/Kubernetes, Azure Pipelines
- Experience with compliance or data security standards relevant to commercial transaction systems
Responsibilities
- Design and build core commercial capabilities — including service bundling, pricing, and markup logic, and margin enforcement across booking scenarios
- Build transactional workflows — including deposit scheduling, payment collection logic, and booking lifecycle event handling
- Develop flexible allocation and payment capabilities — enabling complex booking arrangements across travelers, services, and components
- Own the backend services that underpin commercial accuracy: pricing calculations, margin logic, commission rules, and transactional state management
- Integrate with external services and third-party APIs via secure, well-structured service contracts
- Build and maintain .NET Core microservices within the ADX core platform, with a focus on reliability, correctness, and auditability
- Write and optimize complex SQL Server queries and stored procedures against a large, mature schema
- Design event-driven integrations using Azure Service Bus and NServiceBus for payment lifecycle events and downstream notifications
- Contribute to Angular components where payment workflows surface in the advisor-facing UI
- Support deployment and operations through Azure Pipelines, Docker, and Kubernetes
